Unlike the case of the conventional lens, the light focusing via a scattering lens [1]}, [2]}, [3]}, [4]}, [5]}, [6]} actually contains two indispensable processes: (I) multiple scattering of light inside the scattering lens and (II) shaping the wavefront of light before the light transporting through the scattering lens. As a matter of fact, wavefront shaping is an emerging technology for optical imaging and focusing through disordered media [5]}, [6]}, [9]}, by modulating the incident wavefront, which paves a way for manipulating the scattered light in an expected pattern. Generally, wavefront shaping can be performed by a spatial light modulator in experiment as shown in Fig. REF . The spatial light modulator acting as a reprogrammable matrix of pixels imprints desired phase values on the coherent wavefront.
